I have a 2017 Yukon SLE with 6400 lb towing capacity and tow a 19' camper with GVWR 3626 lb using a weight distribution hitch with integral anti sway (Equal-i-zer). I'll be taking this combination across the country (and back) including through the Rockies from Yellowstone to Flagstaff to Santa Fe. The rig tows fine on the (reasonably) flat east coast I81/I84 corridors (I've towed this rig about 8K miles in this area) but I don't know how it will do on the regular 6%-7% grades (some reported as long as 10 miles) I'll encounter on I15/I78/US89. Anybody have any thoughts?
In addition to tow/haul mode and downshifting on decent is there any advantage/disadvantage to using 4WD vs 2WD? I figure to stay mostly on interstates (Ixx) and US highways (USxx) which are presumably built with trucks in mind. Any other advice?
